All this fuss because the EU is worried that Ireland will get more powerful vacuum cleaners than they have in Brussels?

I think the EU just wants to make leaving it as hard as possible for any other country which might think about it (Poland? Czechia?). Since no-deal supposedly means a hard border between RoI and NI, and the EU is willing to accept no-deal, we have either of the two:
a) the EU is willing to accept the hard border between RoI and NI
b) the EU can maintain open border between RoI and NI even in the event of a no-deal
If it's a), then the EU's claims of rock-solid solidarity with Ireland are lies [1]. If it's b), then the backstop is not a necessary guarantee of an open border between RoI and NI, so why is the EU insisting on it?

[1] Or maybe not. Pumice is a type of rock, too.
